Referring to the drawings, and more particularly to Figs. l to 3, there is shown a metal window prepared from extruded longitudinal elements and consisting of a Ziiid'l Patented Sept. l0, 1957 window frame generally designated by the letter A and a window sash generally designated by the letter B.

The window frame A comprises a plurality of tubular extruded metal sill members 1. The sill members 1 are disposed exteriorly of the face of the building into which the window is inserted. A window frame extruded structural element, generally designated by the numeral 2, is Secured to the sill structure of the building, generally designated by he numeral 3, by means of nut and bolt assemblies 4i. The extruded tubular sill l. is secured to the structural extruded metal window element 2 by means of a plurality of removable screws 5, a longitudinal separator plate 6 of noncompressible material, for example Micarta or other nonmetallic material, is disposed between the sill l. and the window element 2 to effect a lirm rattleproof and watertight seal between the elements l and 2. f

The sash B comprises a plurality of longitudinal extruded tubular elements 7 having U-shaped recesses therein, said recesses being disposed outwardly of the elements 7. In the embodiment of this invention shown in the drawings, -a rectangular sash and window sill is shown, but it is apparent that other coniigurations such as live-sided, sixnsided and other windows and sash are operable within the scope of this invention. The sash B is provided at its interior, centrally disposed and secured to both the top and bottom longitudinal elements, with a pivot housing 8. Interiorly of the pivot housingl 8 (Fig. 3) is a pivot yoke 9. The yoke 9 is provided with a centrally disposed aperture l0, and a pivot pin lil is disposed therein. The yoke 9 is secured to the sash B through the tubular elements 7 having apertures provided therein to receive securing bolts 12. To effect a iirm grip of the bolts l2 tothe sash B, a filler block 13 is disposed within the tubular elements 7 and provided with screw threaded apertures to receive bolts l2.

The extruded tubular sash member 7 has a substantially T-shaped opening or aperture, and the shape of the extrusion itself is generally T-shaped having the longitudinal walls 14 of the T section of theextrusion disposed outwardly toward the sill l, when the sash is disposed in a closed position (Fig. 2). The base l5 of the stem of the T -shaped extrusion 7 is provided with a pair of securing ridges lo.

y A noncompressible plate piece 17, for example Micarta Vor other synthetic material, is disposed upon the ridges i6 and a iirst longitudinal support member 1S of extruded metal is disposed over the noncompressible plate piece i7. A locking plate 19 is provided with screw holes, not shown, and adapted to be secured by means of conventional screws, not shown, through members l and 17 and into the ridges 16. The locking plate 19 is provided with a U-shaped end section generally designated by the numeral 20.

The glass Window pane employed in the sash of this invention is preferably of the Thermopane variety, namely double wall glass window pane 2l., forinsulation against transmission of heat and cold. The insulating window pane, for example Thermopane, is disposed between a T section of the tubular element 7 and the U shaped section 2) of locking plate 19. The window pane 2t? is separated from contact with the metal of extruded element 7 by means of longitudinal spacer bars 22. The window pane 2l is iirmly held in place between extruded eiernents 7 and 19 by means of conventional putty 23. y

it is apparent thaty if the window pane 21 is broken and therefore is to be replaced, removal of the locking plate i9 by removal of thescrews, not shown, for securing said plate 19 will permit insertion of a new window pane.

Vertically disposed U-shaped recesses of the sash B are provided with a plurality of slotted flanges 24. These slotted tlanges 24 are secured to that section of the stem of the T-shaped tubular element 7 that is disposed away from the window pane 21, and constitutes the base of the recess. In other words, the U-shaped recess of the tubularelements 7 which are disposed vabout the four sides of the rectangular sash i B are provided with slotted anges 24 only in the vertically disposed tubular elements 7. The slots of the anges 24 are disposed at an oblique angle upwardly from the horizontal plane and away from the window pane 21. Manifestly the ilanges 24 on the two vertical sides of the sash are disposed in opposed relation (Figs. 6 and 7).

A plurality of U-shaped pressure bars, consisting of a top pressure bar 25, two lateral pressure bars 26 and a bottom `pressure bar 27, are disposed within the U-shaped recesses of tubular elements 7. These pressure bars 25, 26 and 27 are movably secured to one another and `adapted to move toward or away from the center or" the window pane 21. Thepressure bars 2,5, 26 and 27 are motivatedby means of a hand operated worm and gear assembly 2S, shown in detail in Fig. 8. The pressure bars 26 disposed on each side of the window sash are provided `with a plurality of pins 29, which pins traverse the two legs of the U-shaped bars and are adapted to engage the slots of the lianges 24. The worm and gear assembly 28` is provided with a housing `30 and a key operated worm gear'31. The worm gear 31 is adapted to rotate the second worm gear 32 disposed at substantially right angles to the gear 31. The gear 32 is adapted to rotate both a left-handed threaded rod 33 and a rightvhanded threaded rod 34 by conventional means, not

shown;

The left-handed threaded rod 33 is threadingly disposed within a left travel block 35, and the right-handed threaded rod 34 is threadingly disposed into a right travel block 36. Rotation of the worm gear 31 causes the travel blocks 35 and 36 to move away from or toward each other, depending upon the direction of rotation of the worm gear 31. The travel blocks 35 and 36 are provided with movable link bars 37 secured to said blocks and to the bottom U-shaped pressure bar 27, so that outward movement of the travel blocks 35 and 36y will effect outward movement of the pressure bar 27 away from the window pane 21 (Fig. 5).

The travel block 35'is pivotally secured by means of adjustable link` 38 to one of the lateral U-shaped pressure bars 26, and the travel block 36 is pivotally secured by means of adjustable link 39 to the other of the lateral U-shaped bars 26. `As can be seen in Figs. and 6, simultaneousoutward movement of the travel bars and 36 causes simultaneous outward movement of the lateral U- shaped pressure bars26 away `from one another and therefore away from the fixed window pane 21 of the sash B. Conversely, inward movement of the travel blocks 35 and 36 causes inward movement of the pressure bars 26 with the pins 29 slidingly engaging the slots of the xed .anges 24.`

In order to eect inward and outward movement of the top` U-shaped pressure bar 25, the lateral pressure bars 26 are secured at their tops to corner flanges 40 which overhang and embrace the pressure bar 25. The said top pressure bar 25`is provided with blocks 41 (Fig. 2), and a rod 42 is fixed to the outermost block and is slidablein the innermost block. Each corner flange is secured to the outermost block by a screw 44, the said top.,surfaces of the pressurebar 25 being slotted to permit movement of said screw with the block in which it is projected. A transverse pin 43 is secured to one end of each outermost block 41 and in each case is disposed under aifinger of the appropriate corner lange 40. It isapparent that the combined youtward and upward movement of each `lateral pressure bar 26 releases the top pressure bar 25, whereasthe combined inward and downward movement of the lateral pressure bars causes the corner flanges to bear down on the block pins 43. The

lll

downward movement of the outer block, in each case, will be transmitted to the innerblock by the rod, and the downward pressure will substantially be equalized both centrally and at the ends of the said upper pressure bar.

The bottom U-shaped pressure bar 27 is movably secured to the lateral U-shaped pressure bar 26 by means of corner lianges 45 (Fig. 9) having longitudinal slots 46 in each of the lugs of the corner flanges. The corner flanges 45 are movably secured to their respective lJ-shaped bars 26 and the bottom bar 27 by means of headed vbolts 47, the head of the bolts being such as to engage the side walls of the slots.

The resilient peripheral weather strip 48 is disposed t, about the sash. and exteriorly of the pressure bars 25, 26

andZ. The resilient weather strip 48 is preferably made of rubber or synthetic rubber, or other equivalent flexible material, and is preferably of thetcross section configuration shown in Figs. 2, 10 and ll. This cross section contiguration of the resilient weather strip 48 :is such as to possess a pair of substantially circular apertured pressure engaging sections adapted to engage the pressure bar of the sash and corresponding ridge 49 of both the sill 1 and the window structural element 2.

The weather strip 48 is secured to the T-shaped tubular extruded member 7 of the sash by means of longitudinal securing strips 50.` These longitudinal securing strips 50 are removably secured to the respective `sections of the shaft by conventional means, Afor example, removable screws, not shown. The weather strip 48 is so disposed about the pressure bars 25, 26 and 27 `and the corresponding corner anges 40 and 45 so as to present anexterior surface adapted to lbe moved outwardly by the outward movement of the pressure -bars and their corresponding corner anges 4G and 45. The weather strip 48 is disposed on top of the corner flanges 40 and 45, thereby preventing the pinching of the strip 48 by inward movement of the pressure bars 25, 26 and 27 at the respective corners thereof. Y

The pivot yoke 9 is separated-from the `window structural frame piece 2 by means of a washer 51 (Fig. 7). A pair of spring loaded snap pressure securing pins 52 are secured interiorly of the housing and to the yoke 9. These snap pins 52 effect a tight t of the yoke to the pivot housing 8. The pivot pin 11 is disposed through a respective aperture in the window structural member 2 and into a suitable aperture provided therefor in the building structural framework 3.

. `ln the operation of the pivoted window of this invention, the window sash B, after being unlatched from securing latches of conventional` design, generally shown by the numeral 53, may be `rotated through an angle, as shown in Fig. 4, thereby permitting cleaning of the pane surfaces which normally lie outside of the buildingf The window of this invention is` particularly` adapted to produce a weathertight seal against rain and the elements in general upon closing the window .so` that the weather strip 48 engages the coacting ridges 49 of the sill 1 and window yframe piece 2.

A particularly effective 'weathertight position is obtainedby this invention by rotation of the worm gear 31, thereby causing simultaneous outward movement of all four U-shaped pressure bars 25, 26 and 27 along with outwardly disposed movement of the corresponding corner Iianges 4d and 45. Thisoutward movement of the pressure 'bars and their corresponding flanges causes an outward movement of the peripherally disposed resilient rubber weather strip 43 causingl the circular tubular sections of the weather stri-p 1,48 to firmly and vigorously engage the ridges 49 against any possible seepage of rain through the seal formed between the strip 48 and the corresponding longitudinal ridges 49. i 4
